The fleeting, trailed to the U.S. Court of Appeals for the Federal Circuit, aims to overrule a federal jury’s decision in May that Google did nothing unlawful. The appeal is the new iteration of the quarrel which formally started in 2010 and has since been to 2 federal trials and many appeals courts.

Oracle struggles in the 7-year legal battle that Google’s use of Oracle software, exactly its use of Java API in its Android OS, disrupts copyright law.

“When a copyist takes the maximum recognizable portions of a novel and adapts them into a film, the copyist commits the ‘classic’ unfair use,” Oracle wrote in their appeal referencing ‘fair use’ provisions in copyright law. “Google’s copying, in this case, is the software equivalent of this classic unfair use.”

Google weakened to comment on the appeal. In May, however, Google delivered a statement in support of the jury’s decision.

“Today’s verdict that Android makes fair use of Java APIs represents a win for the Android ecosystem, for the Java programming communal, and for software developers who depends on open and free programming languages to build new consumer products,” a Google spokesperson stated.

The jury that issued the conclusion in May stated that Google’s actions were legal under “fair use” in copyright law — the doctrine that extracts of copyrighted material can be legally used without permission in some circumstances.

Oracle did not instantly respond to request for a statement on the appeal.

The nearly decade-long legal quarrel is only a part of the bad blood that exists among the 2 companies. In May, a Fortune report observes that Oracle was a contributor to the “The Google Transparency Project,” a non-profit with the communicated purpose of scrutinizing Google. In 2012, Oracle joined an anti-Google lobbying group.
